Now i also send the pitch/noteduration pair of the second melody to the same [midifile] object in order to receive a two-voice-midi-file. But unfortunately both melodies seem to overwrite their noteDurations and hence i have wrong note durations in the midi file.

Are you writing a single track with two MIDI channels or two tracks?

->> to be honest, I can not answer this question. I initialize [midifile] with ...
- filename and fps in one message
- time signature message [255 88 4 4 2 38 8)
- tempo message [255 81 ...(
...before I send it events.


If you use a [track ( message before each event it should keep them separate.


-> Do you mean a track name message like "FF 03 len text Sequence/Track Name" according to http://www.music.mcgill.ca/~ich/classes/mumt306/StandardMIDIfileformat.html at the bottom?


Thank you very much!
